IMPROVEMENTIN DRIVING MECHANISMS FOR DRYING-MACHINES.

Specification forming part of Letters Patent No. 192,397, dated June 26,1877 application filed November 29, 1876.

To all whom it may concern:

Be it known that I, R. J. WALKER, of Philadelphia, county ofPhiladelphia, and State of Pennsylvania, have invented certain new anduseful Improvements in Driving Mechanism for Drying-Machines, whichimprovements are fully set forth in the following specification,reference beinghad to the accompanying drawmgs.

The object of my invention is to regulate the relative speed between thesizing-rollers and the drying-cylinders of drying-machines bytransmitting the motion from the sizingrollers to the drying-cylindersby means of a belt running over the cones A and B.

It is desirable to have textile fabrics not only of a perfectly uniformwidth from end to end in each piece, but also to have all the pieces ofthe same class of goods alike In width. As the goods come from the loomthey possess neither of the above qualifications, and it is necessary tocorrect the width during the finishing process, and in practice theobject is usually accomplished while the goods pass from thesizing-rollers O K.

In the drawings, F represents the drivingshaft, giving motion to thesizing-rollers K O by means of the pinion I and spur-wheel V.

The pulleys usually employed for driving the drying-cylinders L M N aredisplaced in my invention by cones A and B, over which the belt 0 runs.This belt is guided by the double fork D, which is attached to the rodZ, passing through and being supported by the frame of the machine.

The rod Z is provided with a screw-thread, upon which the nut in thehand-wheel Y works, so that by turning the hand-wheel Y the rod Z ismoved longitudinally, and, of course, carries with it the double fork Dand belt 0, so that by simply turning the hand-wheel Y the belt 0 may becaused to travel upon the largest part of the cone A and the smallestpart of the cone B, which would result in the acceleration of the motionof the drying-cylinders, and by turning the hand-wheel in the otherdirection the opposite and intermediate results may be produced, and allof these operations can be performed while the machine is in motion.

Thus a large amount of material and time is saved, which, previous to myinvention, was consumed in the removal or attachment of suitablechange-pulleys, and in the removal and in the application of lapping tothe pul' leys to increase or diminish their diameters.

As it is desirable to weave certain classes of goods of a certain width,and afterward to stretch them during the finishing process, it isnecessary to know the position which the belt G should occupy before thegoods are put upon the machine. For this purpose I provide an index, E,by which the fork D may be set, after its proper position for a certainclass of goods has been determined experimentally.

I do not claim as my invention the cones A and B, broadly; nor do Iclaim anything not mentioned in the following clauses.

What I claim asmy invention isl. The combination of the cones-A and B,fork D, threaded rod Z, and screwed hamlwheel Y with the sizing-rollersO K and drying cylinders L M N, substantially as and for the purposespecified.

2. In combination with the cones A and B, fork D, threaded rod Z,screwed hand-wheel Y, sizing-rollers O K, and drying-cylinders L M N,the index E, substantially as and for the purpose set forth.
